Converting Crystal Date Group to SQL Command

Question

When selecting the option to group on the server, I found that there are requirements in addition to selecting the option.
I have a date grouping in Crystal like the following:
dateadd("d", - weekday({table.date}, crMonday)+1,{table.date})
Can this be converted to a SQL command?

Hi Mark,
Jyothi had given  an excellent query for you,  Congrats Jyothy!!
But she didnt mantioned 'From clouse' on that.
Let me correct that query with an example,
My TableName: Invoice
Primary Key: InvoicePID
Date field:InvoiceDate
Here the query will be
select InvoicePID,  Dateadd(d,-(CASE  WHEN DATEName(dw,Invoice.InvoiceDate ) = 'Monday' THEN 1
                        WHEN DATEName(dw,Invoice.InvoiceDate ) = 'Tuesday' THEN 2     
                         WHEN DATEName(dw,Invoice.InvoiceDate ) = 'Wednesday' THEN 3
                         WHEN DATEName(dw,Invoice.InvoiceDate ) = 'Thursday' THEN 4
                         WHEN DATEName(dw,Invoice.InvoiceDate ) = 'Friday' THEN 5
                         WHEN DATEName(dw,Invoice.InvoiceDate ) = 'Saturday' THEN 6
                         WHEN DATEName(dw,Invoice.InvoiceDate ) = 'Sunday' THEN 7
END
)+1 ,Invoice.InvoiceDate)
from Invoice
You can change the tablename and field with respect to your DB.
